[suggestion] download enhancements

[shakeyourbunny]

Hello,

I really like your changes you added to the downloader, but I have some suggestions:

• use a ".download", ".incomplete", ".inprogress" or ".gogg" to every file that isn't completely downloaded and once it has been finished, remove that suffix.
• don't overwrite (or configurable) already present files, but just rename them to downloadedfile.zip.old.timestamp(yyyymmddhhmmss) or something ;D
• allow multiple chunked download, ie use multiple connections to download a single file, maybe configurable
• use proper timestamps for finished files, ie use the timestampe from the metadata or the last-modified from the server
• skip files that are already downloaded and have the same checksum that the server provides (configurable?)

Great suggestions!

Adding these features will turn Gogg into a professional download manager 😄

BTW:

• Can you implement any of these features and open a pull request?
• Can you give a start to the repo, if you found Gogg useful? 😊

I don't know Go, but it would be interesting to start with it by doing step by step the easier ones and contribute :-)

Grew up with Turbo Pascal ( so the Go syntax isn't that unfamiliar) and currently, I mostly write scripts in bash and doing some Python, but it is enticing ;D
